Reports usages of <code>System.out</code> or <code>System.err</code>.
<p>Such statements are often used for temporary debugging and should be either removed from the production code, or replaced by a more robust
  logging facility.</p>

<p>The provided quick-fix supports <b>SLF4J</b> and <b>Log4j 2</b>.
 It replaces <code>System.out</code> and <code>System.err</code> calls with log calls</p>

<p><b>Example:</b></p>
<pre><code>
  public static void test(Object o) {
    System.out.println("Test: "+ o);
  }
</code></pre>
<p>After the quick-fix is applied:</p>
<pre><code>
  private static final Logger log = LoggerFactory.getLogger(Test.class);

  public static void test(Object o) {
      log.info("Test: {}", o);;
  }
</code></pre>

  Use the <b>Log method for 'System.err'</b> option to specify a method which it is used to log a message for 'System.err' calls.
  Use the <b>Log method for 'System.out'</b> option to specify a method which it is used to log a message for 'System.out' calls.
